The careful optimisation of air flows, carefully selected components and excellent soundproofing of the frame ensure the tested* quietness of the unit.<\/p>\n\n\n\n<p>With Vallox 99 MV units, the sound pressure level remains below 38 dB even when the air flow is above 70 l\/s (LpA dB(A) 10m2). For this reason, it can be installed in larger apartments than other ventilation units with similar air volumes. Being able to install the same ventilation unit in all the apartments of a building, regardless of their size, enables easier ventilation design, procurement, maintenance and user instruction.<\/p>\n\n\n\n<p>Sound pressure levels have been tested in accordance with the ISO 5135:1997 and ISO 3741:2010 standards.<\/p>\n\n\n\n    <div  class=\"Video w-full h-auto mx-auto \" style=\"\">\n        \n                            <iframe class=\"w-full h-auto aspect-video\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/CE_Z2_jWsYM\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n            \n            <\/div>\n\n\n    <\/div>\n<\/div>\n\n\n\n<div style=\"height:31px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n    <div id=\"\" class=\"Block Section overflow-hidden w-full\">\n        <div class=\"Section-content relative max-w-[1088px] mx-auto w-full\">\n            \n\n<h2 class=\"wp-block-heading\">All modern MyVallox features<\/h2>\n\n\n\n<p>The Vallox 99 MV CF and Vallox 99 MV ventilation units are controlled by using the method that suits the location best, e.g., by using an apartment-specific control panel or through the cooker hood. The unit can also be connected to the cloud service or house automation.<\/p>\n\n\n\n<p>The ventilation can also be set to be partly or fully controlled based on the integrated air quality sensors. With the carbon dioxide and humidity sensors, ventilation is boosted automatically and energy efficiently based on the need.<\/p>\n\n\n\n<p>The efficient heat recovery of the unit ensures energy efficiency. The partial bypass of the heat recovery cell maintains the supply air temperature even also in the spring and autumn.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">All unit information in the Vallox MySelecta product selection software<\/h2>\n\n\n\n<p>Vallox 99 MV CF and Vallox 99 MV ventilation units will replace the Vallox 101 MC\/MV models.<\/p>\n\n\n\n<p>The up-to-date unit and calculation information required for ventilation design can be found in the <a href=\"https:\/\/vallox.magicad.cloud\/login\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Vallox MySelecta product selection software<\/strong><\/a>.
